Now I don't know which of those has what advantages over the other and which fits best to my Cleric. There are plenty Wizards on my server and I don't know if there still is that much demand for them. However, they have some nice skills and I always enjoyed being a nuker. I've had a chinese character LVL 45 with Sword/Shield. I like that build very much. However, the Warlock's skills seem to be quite interesting, too. A Warlock would be a totally different experience for me, I think.
Some people told me, a Cleric is best combined with a Wizard as the Warlock already has the ability to regain HP by sucking them out of his opponents. However I would not use the Cleric to heal the Wizard either. I'd rather play them independently, doing a Cleric when a Cleric is needed and a Wizard/Warlock when one of them is needed. I bet there is far more demand for Warlocks in partys, though, simply because there are so many Wizards.
PVP is not that important for me but efficient party play is. So what do you suggest me, Wizard or Warlock?
Thanks in advance
